Specification of Letters Patent.

Patented J une 13, 1916.

Application filed March 22, 1913. Serial No. 756,189.

moreland and State of Pennsylvania, have invented certain new and useful Improve-' ments in Spooling Devices, of whichthe following is a specification.

My invention has relation to mechanism I employed to regulate and control or guide ropes or cables in the coiling and uncoiling operations whereby the cables or ropes are wound or unwound upon the faces of cylindrical winding drums and while not limited to such uses, more particularly relates to the construction and arrangement of a guiding or spooling mechanism whereby the course of the ropes or cables is directed during the winding and unwinding operations involved in coiling and uncoiling ropes or cables wound upon the drums of mine hauls or mine hoists in a series of super posed layers or wraps.

Experience has demonstrated that a cable or rope will not wind upon a drum in even layers or correct pitch, even when there is abundant lead (the distance from the drum, to the nearest sheave wheel or equivalent fixed position of the rope). Upon beginning to wind irregularl .or get out of pitch, the ropes or cables buil up irregularly upon the winding drums with the result that when under a strain or load, as" is the case in the.

irregularly'wound ropes or cables dropping.

from one to a lower level on the drums.

One object of myinvention is to provide a rope guide or spooling device having novel means whereby the rope or cable is evenly coiled upon the winding drum in a series of wraps or coils of uniform pitch. 7

Another object of. the'invention is to pro vide a rope guide or spooling device having improved means by which the cable or re e is guided or controlled while being coiled upon the winding drum in a series of superposed layers or coils of even or uniform itch.

A rther object of my invention is to provide a rope guide or spooling device having a novel construction and arrangement of parts by'the use of which a rope or cable 1s caused to wind and unwind or coil-and unof the winding drum in alternately opposite directions'during the winding and unwinding 0 e'rations. 2,

A still urther object of thisinvention is to provideQa rope guiding or spooling mech-" amsm havlng improved meanswhereby the ropeor cable is maintainedunder a uniform tension in winding and unwinding the cable or rope on the drum.

Still further objectsof the invention will appear hereinafter in the detailed description and appended .claims.

Referring to the accompanying drawings forming art of this specification, Figure 1 is an en elevation showing a spooling device, constructed and arranged and applied for usein connection with the winding drum of a mine-shaft or'mine hoist in accordance with my invention. Fig. 2 is a plan of the apparatus of'Fig. 1 showing the relative position. of the spooling device and winding drum. Fig. 3 is a side elevation of the rope guide and guide operating-mechanism forming the spooling device-comprising this invention. Fig. is a sectional elevation showinga detail in the construction of the connection between the rope guide and guide actuating mechanism by which the ropeguide is reciprocatedand controlled, in the winding operation.

In the accompanying drawings, the numeral 2 designates a rope winding drum secured on a drum shaft 3, theshaft being rotatably mounted in suitable capped bearrigidly secured upon a suitable foundation- 8. Separators 9 formed of channel beams are provided to secure the beams 7, 7, together, the beams and channels being riveted or otherwise secured together in assembled relation. Rigidly mounted upon coil,'a'nd automatically travel across. the face the so-formed base is a frame or housing 10,

. and on opposite ends of the housing are the pans of capped bearings 11, 11, and 12, 12, by which the vertical shafts 13 and 14 are rotatably mounted on the housing 10.

The vertical shaft 13 is provided at an intermediate point in its length with a bevel gear 15 which is keyed to the shaft and is positioned within the gap or throat 16 formed in the housing between the bearings "11, .1'1', and which meshes with the bevel keyed .oraotherwise fastened on one end of 16 b l ed or otherwise secured in position ion the web of one of the beams 7. Fastened .thehorizontal shaft 23. The shaft 23 is mt 'tably mounted in bearings 24, 24, which 1 0 other 3nd of hQjSltft 23 is a sprocket f. chain wheel 25 which'lis'fconnected by means of asprocket'chain'26 (see Figs. 1 and 2) with a sprocket chain wheel 27 positioned on the drum shaft 3, so that when the drum and drum shaft are rotated the shafts 18 and 23 are actuated and caused to rotate the vertical shaft 13 through the connecting bevel gears 15 and 17. The vertical shaft 13 mounted in the bearings 11, 11, and the verticalshaft 14 in the bearings 12, 12, each have a sprocket chain wheel 28 mounted on the upper end thereof and extending around these sprocket chain wheels 28 is an endless sprocket chain 29. Secured on opposite sides of the housing 10 at the ends of the base are brackets 30 by which the horizontally extending ways or track rails 31, 31, are secured to the housing 9. The ways 31 are T-shaped in cross section and the horizontal leg of the TS is secured to the brackets 30. Mounted upon the horizontal track formed above the housing 10 by the ways 31 is a carriage having a frame 32 with grooved track wheels 33 arranged in pairs on opposite sides and at each end of the frame 32 so asto engage with the vertically extending legs 34 and 35 of the T-shaped Ways 31, the lower wheels 33 preventing the carriage frame 32 from lifting or being raised from its track while being moved along the length of the track in the rope guiding or spooling operations. Mounted in openings in the bosses 36, 36, on the carriage frame 32- are two vertical shafts 37, 37, the upper ends of'these shafts engaging the bearings 38, 38, in the upper portion of the angular braces 39. The braces 39 extend downwardly and are secured to the ends of the carriage frame 32 so as to rigidly secure the shafts 37 in their upright position. The parallel vertically extending shafts 37 each have ananti-friction roller 40 rotatably mounted thereon and the rollers are spaced apart a sufficient distance to provide a lengthwise vertical gap 41 between the faces of the rollers 40 to permit the hoisting rope 42 to extend therethrough. In the middle of the length of the carriage frame 32 is a slot 43 extending lengthwise transversely of the width of the frame and movably mounted in this slot is a slide block 44 which reciprocates in the slot 43. The block 44 is provided with guide plates .45 and 46 which overlap and engage with the upper and lower faces of the frame 32 to maintain the block in position while being reciprocated in the slot 43. Rotatably secured in an opening in the slide block 44 is a pin 47 having a head 48 on its lower end and projecting outwardly from one side of the head 48 are lugs or ears 49 by which the pin 47 and slide block 44 are detachably secured to a link of the endless sprocket chain 29extending around the sprocket wheels 28, 28, on the vertical shafts 13 and 14.

- In the operation of my improved apparatus, the parts are assembled as is shown and has been described, with the hoist rope 42 extending through the slot 41 formed between thevertical guide rollers 40, 40, and secured by one end to the rope drum 2.

When the rope drum 2 is started to rotate, the sprocket wheels 27 on the drum shaft 2, through the sprocket chain 26 rotates the sprocket Wheel shaft 18 on the spooling mechanism, and through the spur pinion 22 on one end of this shaft 18 rotates the spur gear 21 and shaft 18, and, through the bevel gears 15 and 17 causes the vertical shaft 13' to rotate in the bearings 11. When this shaft 13 is rotated, the sprocket wheel 28 on its upper end moves the endless sprocket chain 29 secured around this wheel 28 and opposite sprocket wheel 28 on the vertical shaft 14.

As the endless sprocket chain 29 moves from one end toward the other of the track formed by the T.-rails or ways 31, above the housing 10, the guide rollers 40, 40, are caused to move across the width of the face of the rope drum 2, at the same speed at which the rope 42 is wrapped or laid on the rope drum. When the rotating drum 2 has 4 been revolved a sufficient number of times to lay one layer of the rope 42 across its entire face, the carriage will have been moved on its track exactly the same distance as the length of distance between the flanges on opposite ends of the rope drum, less the diameter of the rope 42. Further rotation of the rope drum 2 in the same direction causes the rope to commence to form a second layer upon the drum and begin to wind upon the drum from the'opposite end of the drum and the opposite hand, and in this movement also, of the drum 2, the rope 42 is guided and caused to become. Wrapped upon the drum in the desired uniform pitch by means of the guide rollers 40, 40, continued rotation of the rope drum 2 cansing further movement of "the endless sprocket chain 29 on the vertical shafts 13 and 14, and reversing the direction of movement of the carriage on its track at the proper time intervals.

' At the beginning of the movement which causes the second layer to be formed 9n the rope drum the slide block 44 will have moved from one end to the other of the slot 43 in which it is mounted and will begin to move in the opposite direction, the pin 47 connecting with the endless chain 29 moving on the opposite side of a line drawn through the center of the vertical shafts 13 and 14 during such movement of the .carriage and rope guiding rollers.

The" above described operations are then 7 repeated with each successive pair of layers of the rope laid upon the-rope drum in the hoisting operation, the carriage being reciprocated on its track and the length of travel of the carriage being-equal to the distance between the flanges on the opposite ends of the ropedrum 2, so that when the rope drum is rotated the number of revolutions necessary to lay a complete layer of the rope thereon, the carriage will be automatically caused to change its direction of movement and reverse the direction.

In unwinding. the rope from the drum the same cycle of operations is carried out,.the

guiding rollers reciprocating back and forth from one end to the other of the drum in the same manner as when coiling the rope upon the drum.

The advantages of my invention will be apparent to those skilledin the art. By the use of my improved spooling device the ropes or cables are evenly laid upon the winding drums, the liability of breakage of the ropes and consequent damage and ex? pense beingvery materially reduced.

Modifications in the construction and ar-' rangement of the parts may be made withfined in the appended means connecting the carriage and drum for positively reciprocating the carriage when said rope drum is rotated.

2. In a spooling device for rope winding drums, the combination of a horizontally.

reciprocating carriage movable across the face of the winding drum, said carriage having upwardly extending axially vertical rollers forming a rope guide, a support for said carriage, sprocket wheels on the support having an endless carriage operating sprocket chain thereon, said chain being pivotally connected to the carriage, and means operatively connecting one sprocket wheel to the winding drum shaft whereby the carriage is positively reciprocated when said rope drum is rotated.

3. In a spool'ng device for rope winding drums, the combination of a horizontally reciprocating carriage movable across the face of the winding drum,- 'saidcarriage having upwardly extending axially vertical rollers forming a rope'guide, a support for said carriage, means on the carriage engaging the lower side'of the carriage support to prevent tilting of said carriage, and mechanism operatively connecting the carriage and drum operating mechanism for positively reciprocating the carriage when the rope drum is rotated.-

In testimony whereof, I have hereunto set my hand.
